Liu, Xianjun;Xiang, Mei-hao;Zhou, Wen-jing;Wang, Fenglin;Chu, Xia;Jiang, Jian-hui research published 《 Clicking of organelle-enriched probes for fluorogenic imaging of autophagic and endocytic fluxes》, the research content is summarized as follows. Autophagy and endocytosis are essential in regulating cellular homeostasis and cancer immunotherapeutic responses. Existing methods for autophagy and endocytosis imaging are susceptible to cellular micro-environmental changes, and direct fluorogenic visualization of their fluxes remains challenging. We develop a novel strategy via clicking of organelle-enriched probes (COP), which comprises a pair of trans-cyclooctenol (TCO) and tetrazine probes sep. enriched in lysosomes and mitochondria (in autophagy) or plasma membrane (in endocytosis). These paired probes are merged and boost a fluorogenic click reaction in response to autophagic or endocytic flux that ultimately fuses mitochondria or plasma membrane into lysosomes. We demonstrate that this strategy enables direct visualization of autophagic and endocytic fluxes, and confer insight into correlation of autophagic or endocytic flux to cell surface expression of immunotherapeutic targets such as MHC-I and PD-L1. The COP strategy provides a new paradigm for imaging autophagic and endocytic fluxes, and affords potential for improved cancer immunotherapy using autophagy or endocytosis inhibitors.

Liu, Zhifang;Li, Zuojie;Du, Tao;Chen, Yan;Wang, Qingpeng;Li, Guoshuai;Liu, Min;Zhang, Ning;Li, Dacheng;Han, Jun research published 《 Design, synthesis and biological evaluation of dihydro-2-quinolone platinum(IV) hybrids as antitumor agents displaying mitochondria injury and DNA damage mechanism》, the research content is summarized as follows. The design of novel platinum(IV) complexes with mitochondria injury competence, besides the DNA damage mechanism, is a promising way to develop new platinum drugs. Herein, dihydro-2-quinolone (DHQLO) as a mitocan was incorporated into the platinum(IV) system for the first time to prepare a new series of DHQLO platinum(IV) compounds Complex 1b could effectively inhibit the proliferation of tumor cells in vitro and in vivo. It accumulated at higher levels in both whole cells and DNA, and easily underwent intercellular reduction to release platinum(II) and DHQLO moieties. The released platinum(II) complex caused serious DNA damage by covalent conjunction with the DNA duplex, and remarkably increased the expression of the γ-H2AX protein. Moreover, 1b also caused serious mitochondria injury to induce mitochondrial membrane depolarization and increase ROS generation. Such actions upon DNA and mitochondria activate the p53 apoptotic pathway synergetically in tumor cells by upregulating the protein p53 and apoptotic proteins caspase9 and caspase3, which efficiently promoted the apoptotic death of tumor cells. Compound 1b with such synergic mechanism exhibited great potential in reversing cisplatin resistance and improving antitumor efficacies.

Li, Yanchun;Quan, Jishun;Song, Haoxuan;Li, Dongzhu;Ma, Enlong;Wang, Yanjuan;Ma, Chao research published 《 Novel pyrrolo[2,1-c][1,4]benzodiazepine-3,11-dione (PBD) derivatives as selective HDAC6 inhibitors to suppress tumor metastasis and invasion in vitro and in vivo》, the research content is summarized as follows. Selective inhibition of histone deacetylase 6 (HDAC6) has been emerged as a promising approach to cancer treatment. As a pivotal strategy for drug discovery, mol. hybridization was introduced in this study and a series of pyrrolo[2,1-c][1,4] benzodiazepine-3,11-diones (PBDs) based hydroxamic acids was rationally designed and synthesized as novel selective HDAC6 inhibitors. Preliminary in vitro enzyme inhibition assay and structure-activity relationship (SAR) discussion confirmed our design strategy and met the expectation. Several of the compounds showed high potent against HDAC6 enzyme in vitro, and compound A7 with a long aliphatic linker was revealed to have the similar activity as the pos. control tubastatin A. Further in vitro characterization of A7 demonstrates the metastasis inhibitory potency in MDA-MB-231 cell line and western blotting showed that A7 could induce the upregulation of Ac-α-tubulin, but not induce the excessive acetylation of histone H3, which indicated that the compound had HDAC6 targeting effect in MDA-MB-231 cells. In vivo study revealed that compound A7 has satisfactory inhibitory effects on liver and lung metastasis of breast cancer in mice. Mol. docking released that A7 could fit well with the receptor and interact with some key residues, which lays a foundation for further structural modifications to elucidate the interaction mode between compounds and target protein. This pharmacol. investigation workflow provided a reasonable and reference method to examine the pharmacol. effects of inhibiting HDAC6 with a single mol., either in vitro or in vivo. All of these results suggested that A7 is a promising lead compound that could lead to the further development of novel selective HDAC6 inhibitors for the treatment of tumor metastasis.

Liang, Tao;Zhou, Yi;Elhassan, Reham M.;Hou, Xuben;Yang, Xinying;Fang, Hao research published 《 HDAC-Bax Multiple Ligands Enhance Bax-Dependent Apoptosis in HeLa Cells》, the research content is summarized as follows. Inspired by the synergistic effect of BTSA1 (a Bax activator) and SAHA (a histone deacetylase (HDAC) inhibitor) in HeLa cell growth suppression, a series of novel HDAC-Bax multiple ligands were designed rationally. Compound 23, which possesses similar HDAC inhibitory activity relative to SAHA and Bax affinity comparable to BTSA1, exhibits a superior growth suppression against HeLa cells, and its antiproliferative activities are 15-fold and 3-fold higher than BTSA1 and SAHA, resp. The better antiproliferative activity and lower cytotoxicity of compound 23(I) indicated that our HDAC-Bax multiple ligand design strategy achieved success. Further studies suggested that compound 23 could enhance Bax-dependent apoptosis by upregulating Bax, followed by inducing the conformational activation of Bax. To our knowledge, we first report HDAC-Bax multiple ligands and demonstrate a new paradigm for the treatment of solid tumors by enhancing Bax-dependent apoptosis.

Recently, our group identified that harmine is able to induce β-cell proliferation both in vitro and in vivo, mediated via the DYRK1A-NFAT pathway. Since, harmine suffers from a lack of selectivity, both against other kinases and CNS off-targets, we therefore sought to expand structure-activity relationships for harmine’s DYRK1A activity, to enhance selectivity for off-targets while retaining human β-cell proliferation activity. We carried out optimization of the 9-N-position of harmine to synthesize 29 harmine-based analogs. Several novel inhibitors showed excellent DYRK1A inhibition and human β-cell proliferation capability. An optimized DYRK1A inhibitor, compound I, was identified as a novel, efficacious in vivo lead candidate. Compound I also demonstrates improved selectivity for kinases and CNS off-targets, as well as in vivo efficacy for β-cell proliferation and regeneration at lower doses than harmine. Collectively, these findings demonstrate that compound I is a much improved in vivo lead candidate as compared to harmine for the treatment of diabetes.

Recently, we have shown that harmine induces β-cell proliferation both in vitro and in vivo, mediated via the DYRK1A-NFAT pathway. We explore structure-activity relationships of the 7-position of harmine for both DYRK1A kinase inhibition and β-cell proliferation based on our related previous structure-activity relationship studies of harmine in the context of diabetes and β-cell specific targeting strategies. Thirty three harmine analogs of the 7-position substituent were synthesized and evaluated for biol. activity. Two novel inhibitors were identified which showed DYRK1A inhibition and human β-cell proliferation capability. The DYRK1A inhibitor, compound 3-(7-oxy-1-methyl-9-H-b-carbolin)propionic acid Me ester, induced β-cell proliferation half that of harmine at three times higher concentration From these studies we can draw the inference that 7-position modification is limited for further harmine optimization focused on β-cell proliferation and cell-specific targeting approach for diabetes therapeutics.

A strategy for the synthesis of medium-sized lactones and lactams from linear precursors is described in which an amine acts as an internal nucleophilic catalyst to facilitate a novel cyclisation/ring expansion cascade sequence. This method obviates the need for the high-dilution conditions usually associated with medium-ring cyclisation protocols, as the reactions operate exclusively via kinetically favorable “normal”-sized cyclic transition states. This same feature also enables biaryl-containing medium-sized rings to be prepared with complete atroposelectivity by point-to-axial chirality transfer.

Through a phenotypic high-throughput screen using a serum response element luciferase promoter, we identified a novel 5-aryl-1,3,4-oxadiazol-2-ylthiopropionic acid lead inhibitor of Rho/myocardin-related transcription factor (MRTF)/serum response factor (SRF)-mediated gene transcription with good potency (IC₅₀ = 180 nM). We were able to rapidly improve the cellular potency by 5 orders of magnitude guided by sharply defined and synergistic SAR. The remarkable potency and depth of the SAR, as well as the relatively low mol. weight of the series, suggests, but does not prove, that binding to the unknown mol. target may be occurring through a covalent mechanism. The series nevertheless has no observable cytotoxicity up to 100 μM. Ensuing pharmacokinetic optimization resulted in the development of two potent and orally bioavailable anti-fibrotic agents that were capable of dose-dependently reducing connective tissue growth factor gene expression in vitro as well as significantly reducing the development of bleomycin-induced dermal fibrosis in mice in vivo.
